The common method of achievement and accomplishing your goals is by force. Push harder, put in more time and effort, show up early, stay late.
A lot can be accomplished through effort and exertion.
Another method is to progress through the wisdom of selflessness. As you cut through ego and self-cherishing, you eliminate possessiveness and suffer less. Not fixating on your own agenda and perspective, you become more open and generous.
As wisdom deepens, you don't feel so overwhelmed by situations or problems. You don't feel the need to turn back or give up.
As wisdom deepens further you can work with adverse conditions and circumstances with great patience. The impulse to shut down gradually fades further and further from view.
Deeper still, your wisdom overwhelms whatever arises in your experience, allowing you to continue forward with your intention. Even amidst great hardship and adversity, you continue unafflicted.
Deeper and deeper into the wisdom of selflessness, further and further along the path you progress. Wisdom unearths accomplishment, yet what have you to gain?
